Kubis bunga merupakan sayuran dengan prospek tinggi dalam nilai ekonomi yang 
dibudidayakan di dataran tinggi (Fitriani, 2009). Namun kuantitas dan kualitas produksi 
kubis bunga masih rendah yang disebabkan beberapa faktor (Arpanto & Soenyoto, 2018). 
Salah satu peningkatan produksi kubis bunga dengan pemberian mulsa baik mulsa jerami 
maupun mulsa plastik hitam perak. Tujuan dari penelitian yakni mengetahui pengaruh 
aplikasi jenis mulsa terhadap sifat fisik tanah pada budidaya kubis bunga                    
(Brassica oleracea var. botrythis L.) di lahan marginal dan mengklasifikasi hubungan antar 
variabel sifat fisik tanah yang diamati. Penelitian dilakukan di Dusun Bulusari, Desa Sirau, 
Kecamatan Kemranjen, Kabupaten Banyumas pada Juni hingga September 2024. 
Pengambilan sampel tanah tidak terganggu dilakukan menggunakan ring sampler 
berukuran 100 cm3 setiap 1 minggu sekali selama 5 minggu pengamatan yaitu 7, 14, 21, 
28, dan 35 hari setelah tanam pada 3 kedalaman tanah yaitu, 0 – 10, 10 – 20, dan                     
20 – 30 cm. Pada masing-masing kedalaman dilakukan 3 kali pengulangan pengambilan 
sampel untuk setiap kombinasi perlakuan (P0M0, P1M0, P1M1, dan P1M2) dan diperoleh 
180 sampel. Analisis data menggunakan ANOVA, DMRT 5%, Student T Test, dan 
Analisis Regresi. Hasil penelitian menunjukkan perlakuan mulsa jerasi berpengaruh 
terhadap kadar air tanah basis kering, dry bulk density, porositas tanah, dan permeabilitas 
tanah di lapisan tanah bagian atas. Perlakuan mulsa plastik hitam perak berpengaruh 
terhadap kadar air tanah basis kering, dry bulk density, porositas tanah, dan permeabilitas 
tanah di lapisan tanah bagian bawah. Berdasarkan hasil regresi yang dilakukan, dihasilkan 
beberapa hubungan antar variabel sifat fisik tanah yang diamati. Linier negatif antara dry 
bulk density dan permeabilitas tanah dengan nilai R2 sebesar 0,2080. Linier positif antara 
porositas tanah dan permeabilitas tanah dengan nilai R2 sebesar 0,2080. Linier positif 
antara kadar air tanah basis kering dan permeabilitas tanah dengan nilai R2 sebesar 0,1610.

Cauliflower was a vegetable with high prospects in economic value that was 
cultivated in highland areas (Fitriani, 2009). However, the quantity and quality of 
cauliflower production were still low, caused by several factors (Arpanto & Soenyoto, 
2018). One of the efforts to increase cauliflower production was the application of 
mulch, either straw mulch or silver–black plastic mulch. The objective of this study 
was to determine the effect of mulch type application on soil physical properties in 
cauliflower (Brassica oleracea var. botrytis L.) cultivation on marginal land and to 
classify the relationships among the observed soil physical property variables. The 
research was conducted in Bulusari Hamlet, Sirau Village, Kemranjen Sub-district, 
Banyumas Regency, from June to September 2024. Undisturbed soil sampling was 
carried out using a ring sampler with a volume of 100 cm³ once every week for 5 weeks 
of observation, namely at 7, 14, 21, 28, and 35 days after planting, at three soil depths: 
0–10 cm, 10–20 cm, and 20–30 cm. At each depth, three replications of soil sampling 
were conducted for each treatment combination (P0M0, P1M0, P1M1, and P1M2), 
resulting in a total of 180 samples. Data were analyzed using ANOVA, DMRT at a 5% 
significance level, Student’s T-Test, and regression analysis. The results of the study 
showed that the straw mulch treatment affected soil water content on a dry weight 
basis, dry bulk density, soil porosity, and soil permeability in the upper soil layer. The 
silver–black plastic mulch treatment affected soil water content on a dry weight basis, 
dry bulk density, soil porosity, and soil permeability in the lower soil layer. Based on 
the regression analysis, several relationships among the observed soil physical 
property variables were obtained: a negative linear relationship between dry bulk 
density and soil permeability with an R² value of 0.2080; a positive linear relationship 
between soil porosity and soil permeability with an R² value of 0.2080; and a positive 
linear relationship between soil water content on a dry weight basis and soil 
permeability with an R² value of 0.1610.
